I have read it in a number of different publications. The Asian community has quite a bit of sleep research coming out of China and Japan. I believe that Japan and Canada are the only 2 countries still currently involved in dream research.
Not to overgeneralize about cultures of people, but I am under the impression that Asians as a group are typically health conscious and more open to alternative treatments like acupuncture, herbs, meditation -- wonder how aware they are that they as an ethnicity have a giant bulls-eye on them for Sleep Apnea, and how willing they'd be to use CPAP as compared to Western cultures.
